= Steve Capper - Thanks for the Memory =

As is reasonably well known, the memory system in AArch64 is somewhat
different to that found in x86. In this talk I aim to go through the
salient differences and their ramifications.
In particular I would like to talk about:

 * Lightning overview of ARM/Linux kernel terminology (levels, stages, granule, exception levels).
 * Contiguous hint, how it is implemented in HugeTLB, and what to worry about when handling contiguous PTEs.
 * How user space and kernel performance are affected by 4KB, 64KB and huge pages.
 * When JITs die: tell-tale signs for user space VA space size assumptions.
 * The subtle mistakes I made in TLB invalidation, so you don't have to repeat them ;-).
